The final summer edition of Music on the Square will be Friday in Kingston. Performers will be Air Loom — Dana Louise and Jackson Jennings, pictured — and Emily Kaitz with Drew Pierce. Air Loom, a duo of singer-songwriters from Northwest Arkansas, will charm with sweet harmonies and songs from the heart. Kaitz and Pierce perform on guitar and banjo and sing bluegrass classics coupled with Emily’s quirky original tunes like “Tornado Season in Tulsa,” “To Be A Wood Bee,” “Yuppie Scum” and “If The World Is Warming, Why Are You So Cold?” Music starts at 7 p.m., and admission is free. Sponsors are the Kingston Public Library and Friends of the Library. Information: 957-1089.
